FIELD OF THE INVENTION

The present invention relates to cancer immunotherapy comprising administration of oncolytic virus and one or more immunomodulators.

BACKGROUND OF THE INVENTION

The human immune system of innate and adaptive immunity is an extremely complex system which has not yet been successfully utilized to fight against cancer. One explanation is that, since cancers are usually developed within the later part of life, the development of an immunological response to counteract cancer is not vital to the survival of the fittest theory in the evolutionary process. In all likelihood, the different aspects of the human immune system are not designed specifically for that purpose, meaning to kill cells that are considered as “self”. Even after extensive removal of the primary tumor it is still a problem to prevent the formation of metastases either due to growing out of micro-metastases already present at the time of surgery, or to the formation of new metastases by tumor cells or tumor stem cells that have not been removed completely or being re-attached after surgery. In essence, for later stages of cancer, surgery and/or radiotherapy can only take care of the macroscopic lesions, while most patients will have their cancers recurring and not amenable to further therapies.

More recently FDA has approved two immunotherapeutic agents against prostate cancer and melanoma. The first agent, PROVENGE®, utilizes a GM-CSF fusion molecule with a prostatic antigen to activate the mononuclear or antigen presenting cells of late-stage cancer patients in vitro and is able to prolong the overall survival of these patients. The second agent is an anti-CTLA-4 monoclonal antibody, which was shown to produce a profoundly enhancing effect in T effector cell generation. An oncolytic virus CG0070 has also been shown to trigger a long-term complete response among bladder cancer patients after one series of six weekly intravesical treatments (see Burke J M, et al. Journal of Urology December 188 (6) 2391-7, 2012).

Current cancer immunotherapy methods face various fundamental challenges. For example, normally tumor-specific immune T lymphocytes in cancer patients, even when they are present, only occur at low frequency systemically. The likely reason is that the antigenicity and specific immunogenicity of common cancers' tumor antigens are generally weak, as well as the presence of an overwhelming amount of suppressor activities through cytokines and regulatory cells, such as Treg, tumor associated macrophages, etc. Additionally, the older concepts of using nonspecific components to boost immune response against specific components were found to have little success, as the ability for a human body to generate very specific immunological responses against its own cells is limited by nature. After all, most cancer cells are not immunogenic enough to be different from normal cells. Such an immune response derived from non-specific immunological components, even if generated, will also be short-lived.

For at least the reasons discussed above, in vitro and pre-formulated therapeutic cancer vaccines using available tumor antigens and adjuvants have been tried for decades without much success. There is a clear need for cancer immunotherapy methods with improved efficacy.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic diagram of CG0070 and wild type (wt) adenovirus type 5. CG0070 is based on adenovirus serotype 5, but the endogenous E1a promoter and E3 19kD coding region have been replaced by the human E2F-1 promoter and a cDNA coding region of human GM-CSF, respectively.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides methods and compositions for treating a solid or lymphatic tumor in an individual by locally administering to the site of a tumor an effective amount of an oncolytic virus (such as CG0070), and systemically administering an effective amount of an immunomodulator (including combination of immunomodulators, such as an immune-stimulating agent and/or an immune checkpoint inhibitor). The methods and compositions may further comprise local administration of an immunomodulator (including combination of immunomodulators). For example, one exemplary tumor suitable for methods described herein is bladder cancer, and the oncolytic virus can be administered intravesically, while the immunomodulator can be administered intravenously.

The present invention provides a live and real time “in vivo” cancer vaccine system generated inside a human body by local (such as intratumoral) delivery of an oncolytic virus in combination with systemic (such as intravenous) delivery of an immunomodulator. A distinguishing feature of the present invention is the oncolytic virus, which has both a tumor cell-specific promoter operably linked to a viral gene essential for replication, and a heterologous gene encoding an immune-related molecule, such as GM-CSF. Thereby, local administration of the oncolytic virus allows both tumor-specific infections by the virus, and simultaneous local delivery of the immune-related molecule to the tumor site. Further combined with systemic delivery of an immunomodulator (including combination of immunomodulators) and optionally local administration of a second immunomodulator (including combination of immunomodulators), the cancer vaccine system may provide the therapeutic components at the right effective amounts, at the right timing, and in the right sequences to the tumor and the human body to elicit an enhanced immune response against the tumor.

It is thus believed that the combination described herein would allow full exploitation of the oncolytic and immunogenic reactions in the individual, and increase the therapeutic potential of the cancer immunotherapy. It is to be understood by a person of ordinary skill in the art that the combination therapy methods described herein requires that one agent or composition be administered in conjunction with another agent. The dosage, dosing schedule, rmutes of administration, and sequence of administration for each agent in the combination therapy provided herein (such as the oncolytic virus, and each immunomodulator) can be independently optimized to provide optimal therapeutic results. The methods may also be further combined with local administration of inactivated tumor cells, and/or pretreatment, such as local radiation, or local administration of cytokines, chemokines, or other beneficial therapeutic agent, to increase the chance of success for the therapy.

In one aspect, there is provided a method of treating a solid or lymphatic tumor in an individual, comprising: a) locally administering to the site of the tumor an effective amount of an oncolytic virus; and b) systemically administering an effective amount of an immunomodulator (including combination of immunomodulators), wherein the oncolytic virus comprises a viral vector comprising a tumor cell-specific promoter operably linked to a viral gene essential for replication of the virus, and a heterologous gene encoding an immune-related molecule.

The present invention is based in part on unpublished results from our clinical trials. Without being bound by any theory or hypothesis, it is believed that the viral oncolytic virus, CG0070, which is specifically designed to replicate only in cancer cells, provides the “right amount” of GM-CSF at tumor sites and in “real time” during cancer cell death. This “at” tumor site delivery of GM-CSF by the oncolytic virus during cancer cell death is believed to be vital for antigen presenting cells to both mature and to cross present established antigens, neoantigens, and tolerance breaking antigens (TBA) from this cell death mixture to the activated T cells. The right amount of GM-CSF is needed at the tumor site in this therapeutic scenario, because a high dose of GM-CSF would render the immune system without a focus, and trigger an instantaneous increase of local and system suppressors; whereas a low dose of GM-CSF would not be enough for the activation of the inflammatory process and the related immune cells. A delicate balance at the tumor site involving the right amount of GM-CSF and the on-site “live” cancer cell death mixture is believed to elicit an adaptive immune response that is specific to cancer cells. Therefore, an oncolytic virus that is cancer specific and oncolytic, and in combination with the right amount of GM-CSF or other appropriate immune-related molecules either expressed by the oncolytic virus or secreted by body defense in response to any oncolytic virus during cell death, infection or inflammation, delivered “at” the tumor sites, are believed to be an ideal choice for effective cancer immunotherapy.

In some embodiments, the pretreatment step comprises administrating directly or indirectly (e.g. through an intravenous route) to the luminal surface of the bladder in the individual an effective amount of a therapeutic agent prior to the administration of the oncolytic virus and the immunomodulator (including combination of immunomodulators). In some embodiments, the therapeutic agent is any one or combination of chemotherapeutic agents known in the art, for example, cyclosphamide. In some embodiments, the therapeutic agent is any one or combination of agents targeting or blocking a cellular signaling pathway known in the art, for example, a BRAF inhibitor. In some embodiments, the therapeutic agent is any one or combination of cell therapies known in the art, for example, TIL cells, CAR/T cells, and/or TCR/T cells. In some embodiments, the therapeutic agent is an agent that increases the level of cytokines involved an immunogenic pathway.

In some embodiments, the therapeutic agent induces immune cells, such as dendritic cells, B cells, and T cells (such as follicular T helper cells).

Combination Therapy with Tumor Cells

Any of the methods described above can be combined with local administration to the tumor site a plurality of inactivated tumor cells.

Accordingly, one aspect of the present application relates to methods of treating a solid or lymphatic tumor in an individual (such as a human), comprising: a) locally administering to the site of the tumor an effective amount of an oncolytic virus; b) systemically administering an effective amount of an immunomodulator (including combination of immunomodulators); and c) locally administering to the site of the tumor an effective amount of inactivated tumor cells, wherein the oncolytic virus comprises a viral vector comprising a tumor cell-specific promoter operably linked to a viral gene essential for replication of the virus, and a heterologous gene encoding an immune-related molecule. In some embodiments, there is provided a method of treating a solid or lymphatic tumor in an individual (such as a human), comprising: a) locally administering to the site of the tumor an effective amount of an oncolytic virus; b) systemically administering an effective amount of an immunomodulator (including combination of immunomodulators); c) locally administering to the site of the tumor an effective amount of a second immunomodulator (including combination of immunomodulators); and d) locally administering to the site of the tumor an effective amount of inactivated tumor cells, wherein the oncolytic virus comprises a viral vector comprising a tumor cell-specific promoter operably linked to a viral gene essential for replication of the virus, and a heterologous gene encoding an immune-related molecule. This at least three-component combination therapy method may comprise any embodiment of the methods described above for the combination therapy comprising the oncolytic virus and the immunomodulator (including combination of immunomodulators). The present combination therapy method comprising the inactivated tumor cells is advantageous over other cancer immunotherapy methods involving similar components, because administration parameters, such as dosage, dosing frequency and/or route of administration, for each of the three components, namely, the oncolytic virus (such as oncolytic virus, for example, oncolytic adenovirus), the immunomodulator (including combination of immunomodulators), and the inactivated tumor cells can be independently adjusted to optimize the efficacy and minimize the toxicity of the therapy to the individual.

Without being bound by any theory or hypothesis, it is believed that in this three-component combination therapy, an outside source of inactivated but live tumor cells (also referred herein as “live cancer cells” or “live tumor cells”), whether they are autologous or allogeneic in origin, could provide an additional, yet important source of new antigens when administered at the site of the tumor. Outside source in this context means that these tumor cells have already been removed previously, from the same individual or from another individual. The cells may have further been subjected to in vitro culture for expansion, cryopreservation, thawing and characterization. It is believed that this outside source of inactivated tumor cells can sometimes stimulate not only a T cell response, but may also solicit a B cell, and sometimes trigger a massive antibody response that is synergistic with the oncolytic virus (such as virus), and the immunomodulator (including combination of immunomodulators) as described previously.

Thus, in some embodiments, there is provided a method of treating a solid or lymphatic tumor in an individual, comprising: a) locally administering to the site of the tumor an effective amount of an oncolytic virus; b) systemically administering an effective amount of an immunomodulator (including combination of immunomodulators); and c) locally administering to the site of the tumor an effective amount of inactivated tumor cells, wherein the oncolytic virus comprises a viral vector comprising a tumor cell-specific promoter operably linked to a viral gene essential for replication of the virus, and a heterologous gene encoding an immune-related molecule.

In some embodiments, the inactivated tumor cells are transduced and genetically modified by the oncolytic virus used in the combination therapy.

Tumor cells may be isolated from a tissue, a resected tumor, or a tumor biopsy by any of the methods known in the art, including, but not limited to mechanical, enzymatic separation methods, and combinations thereof. For example, a mixture of collagenase. DNase and hyaluronidase can be used to incubate tumor specimen to obtain the inactivated tumor cells. In some embodiments, multiple batches of isolated autologous tumor cells are obtained from the solid or lymphatic tumor or metastatic sites of the individual during the course of treatment. In some embodiments, the inactivated tumor cells are cryopreserved prior to inactivation.

Since cancer cells, particular in metastatic sites, are heterogeneous mixtures of different clones of cells undergoing rapid replications and frequent mutations, it is sometimes preferable to have a specific component that may adapt to these changes while or when they do occur. Autologous tumor cells can be prepared from the original surgical specimen, biopsies or from removal of metastatic lesions later on. One of the advantages of this method is that the autologous tumor cells can be changed according to the patient's response and the availability of tumor samples. For example, a tumor-oncolytic virus (e.g. virus) live and in vivo vaccine system generated in the primary tumor phase may be different from the one generated later on, using tumor cells from metastatic sites. The ultimate goal, in some embodiments, is to adapt the immunotherapeutic response according to the prevailing tumor types, an advantage that cannot be found in recent development of pathway-targeted therapy or monoclonal antibody-directed therapy.

The inactivated tumor cells are inactivated prior to the administration. Typically, the inactivated tumor cells are proliferation incompetent. Tumor cells can be inactivated with any of the known method in the art. In some embodiments, the inactivated tumor cells are inactivated by irradiation. In some embodiments, the inactivated tumor cells are irradiated at a dose of from about 50 to about 200 rads/min, or from about 120 to about 140 rads/min prior to administration to the patient. In some embodiments, the inactivated tumor cells are irradiated with a total dose of about any one of 2,500 rads, 5,000 rads, 10,000 rads, 15,000 rads or 20.000 rads. In some embodiments, the inactivated tumor cells are irradiated with a total dose of from about 10,000 to about 20.000 rads. In some embodiments, the inactivated tumor cells are irradiated with a total dose sufficient to inhibit substantially 100% of the cells, from further proliferation. In some embodiments, wherein the inactivated tumor cells are genetically modified, the total dose of irradiation is insufficient to inhibit expression or secretion of the immune-related molecule, such as GM-CSF. In some embodiments, the total dose of irradiation is insufficient to inhibit transduction or genetic modification of the inactivated tumor cells by the oncolytic virus upon administration. In some embodiments, the inactivated tumor cells are cryopreserved prior to the administration.

The inactivated tumor cells are administered intratumorally, for example, by intratumoral injection. Suitable dosage of the inactivated tumor cells for administration depends on the status (e.g., microenvironment, type, stage etc.) of the solid or lymphatic tumor and other diagnostic and risk factors of the individual. In some embodiments, a suitable dosage of the inactivated tumor cells is about any one of 1×10³, 1×10⁴. 1×10⁵, 2×10⁵, 5×10⁵, 1×10⁶, 2×10⁶, 5×10⁶. 1×10⁷, 5×10⁷, or 1×10⁸ cells. In some embodiments, a suitable dosage of the inactivated tumor cells is any one of about 1×10³ to about 1×10⁴, about 1×10⁴ to about 1×10⁵, about 1×10⁵ to about 2×10⁵, about 2×10⁵ to about 5×10⁵, about 5×10⁵ to about 10⁶, about 10⁶ to about 2×10⁶, about 2×10⁶ to about 5×10⁶, about 5×10⁶ to about 1×10⁷, about 1×10⁷ to about 5×10⁷, or about 5×10⁷ to about 1×10⁸ tumor cells. In some embodiments, the dosage of the inactivated tumor cells is calculated as cells/Kg of body weight.

In some embodiments, the relative ratio of the oncolytic virus (such as virus) to the inactivated tumor cells is based on the multiplicity of infection (MOI) index calculated using the number of oncolytic virus particles to the number of the inactivated tumor cells alone or to the total number of live tumor cells including the inactivated tumor cells and the estimated number of live tumor cells at the administration site. In some embodiments, the MOI is at least about any one of 1, 2, 5, 10, 50, 100, 200, 500, 1000, 5000, 10⁴, 10⁵, 10⁶, or more. In some embodiments, the oncolytic virus is provided in an amount proportional to the volume of the estimated tumor sites. In some embodiments, the inactivated tumor cells are provided in an amount limited by preparations from tumor biopsy, tumor resection, tumor cell culture and other methods for isolating tumor cells known to the art. In some embodiments, the oncolytic virus is provided in the composition at about 1×10⁵ particles to about 1×10¹⁴ particles (for example, about 1×10¹² particles).

Oncolytic Viruses

The methods and compositions described herein are related to oncolytic viruses, such as a viral vector, for example, oncolytic adenovirus. The oncolytic virus may be a genetically modified oncolytic virus, for example an attenuated oncolytic virus, and the oncolytic virus has additional favorable features (e.g., preferential replication in cancer cells, and encoding an immune-related molecule).

Exemplary viruses that are suitable for use in the present invention include, but are not limited to, adenovirus, for example, H101 (ONCOCRINE®), CG-TG-102 (Ad5/3-D24-GM-CSF), and CG0070; herpes simplex virus, for example, Talimogene laherparapvec (T-VEC) and HSV-1716 (SEPREHVIR®); reo virus, for example, REOLYSIN®; vaccinia virus, for example, JX-594; Seneca valley virus, for example, NTX-010 and SV V-001; Newcastle disease virus, for example, NDV-NS1 and GL-ONC1; polio virus, for example, PVS-RIPO; measles virus, for example, MV-NIS; coxsackie virus, for example, CAVATAK™; vesicular stomatitis virus; maraba and rhabdoviruses; parvovirus and mumps virus.

The viral vector of the oncolytic virus (such as oncolytic adenovirus) further comprises a heterologous gene encoding an immune-related molecule (such as cytokine or chemokine). In some embodiments, the heterologous gene is operably linked to a viral promoter. In some embodiments, the viral promoter is the E3 promoter.

In some embodiments, the oncolytic virus is an adenovirus serotype 5, wherein the endogenous E1a promoter of a native adenovirus is replaced by the human E2F-1 promoter and E3 19kD coding region of the native adenovirus is replaced by a nucleic acid encoding an immune-related molecule (such as cytokine or chemokine, for example, GM-CSF). In some embodiments, the tumor-specific promoter is a human E2F-1 promoter or an E2F-1 promoter comprising the nucleotide sequence set forth in SEQ ID NO: 1.

In some embodiments, the oncolytic virus is CG0070, an adenovirus serotype 5 which has an E2F promoter at the E1a gene and a GM-CSF expression at the E3 gene.

CG0070 is a conditionally replicating oncolytic adenovirus (serotype 5) designed to preferentially replicate in and kill Rb pathway-defective cancer cells. This vector is transcriptionally regulated by a promoter (e.g., E2F-1 promoter) that is up-regulated in Rb-pathway-detective tumor cells. In approximately 85% of all cancers, one or more genes of the Rb pathway, such as the tumor suppressor Rb gene, are mutated. In addition to its restricted propagation. CG0070 also encodes the human cytokine GM-CSF, which is expressed selectively in the infected tumor cells to stimulate immune responses against uninfected distant (such as metastases) and local tumor foci.

The genomic structure of the oncolytic adenoviral vector CG0070 is shown schematically in FIG. 1. Products of the adenoviral early E1A gene are essential for efficient expression of other regions of the adenoviral genome. CG0070 has been engineered to express the E1A gene under control of the human E2F-1 promoter, which provides tumor specificity to the E1A gene product. To protect from transcriptional read-through activating E1A expression, a polyadenylation signal (PA) was inserted 5′ of the E2F-1 promoter. CG0070 includes the entire wild type E3 region except for the 19kD-coding region. A direct comparison of E3-containing to E3-deleted oncolytic adenovirus vectors showed superiority of E3-containing vectors in tumor spread and efficacy. In place of the 19kD gene, CG0070 carries the cDNA for human GM-CSF under the control of the endogenous E3 promoter (E3P). Since the E3 promoter is in turn activated by E1A, both viral replication and GM-CSF expression are ultimately under the control of the E2F-1 promoter. The rest of the viral vector backbone, including the E2, E4, late protein regions and inverted terminal repeats (ITRs), is identical to the wild type Ad5 genome.

CG0070 is manufactured in HeLa-S3 cells, and released from infected HeLa-S3 cells by detergent lysis. CG0070 is purified from the lysate by chromatography, and then formulated in 5% sucrose, 10 mM Tris, 0.05% polysorbate-80, 1% glycine, 1 mM magnesium chloride. pH 7.8.

CG0070 is supplied as a sterile, slightly opalescent, frozen liquid in stoppered glass vials. The particle concentration per mL (vp/mL) is stated on the Certificate of Analysis for each lot of CG0070.

CG0070 has additional potential anti-tumor activity in that it carries the cDNA for human GM-CSF, a key cytokine for generating long-lasting anti-tumor immunity. Thus, CG0070 is a selectively replicating oncolytic vector with the potential for attacking the tumor by two mechanisms: direct cytotoxicity as a replicating vector and induction of a host immune response. Summarized in the following sections are in vitro and in vivo studies conducted to characterize the tumor selectivity and anti-tumor activity and safety of CG0070.

Immunomodulators

The methods of the present invention in some embodiments comprise administration of an oncolytic virus with an immunomodulator (including combination of immunomodulators).

“Immunomodulator” refers to an agent that when present, alters, suppresses or stimulates the body's immune system. Immunomodulators can target specific molecules, such as the checkpoint molecules, or non-specifically modulate the immune response. Immunomodulators can include compositions or formulations that activate the immune system (e.g., adjuvants or activators), or downregulate the immune system. Adjuvants can include aluminum-based compositions, as well as compositions that include bacterial or mycobacterial cell wall components. Activators can include molecules that activate antigen presenting cells to stimulate the cellular immune response. For example, activators can be immunostimulant peptides. Activators can include, but are not limited to, agonists of toll-like receptors TLR-2, 3, 4, 6, 7, 8, or 9, granulocyte macrophage colony stimulating factor (GM-CSF); TNF; CD40L; CD28; FLT-3 ligand; or cytokines such as IL-1, IL-2, IL-4, IL-7, IL-12, IL-15, or IL-21. Activators can include agonists of activating receptors (including co-stimulatory receptors) on T cells, such as an agonist (e.g., agonistic antibody) of CD28. OX40, GITR. CD137, CD27, CD40, or HVEM. Activators can also include compounds that inhibit the activity of an immune suppressor, such as an inhibitor of the immune suppressors IL-10, IL-35, TGF-β, IDO, or cyclophosphamide, or inhibit the activity of an immune checkpoint such as an antagonist (e.g., antagonistic antibody) of CTLA-4. PD-1, PD-L1. PD-L2, LAG3, B7-1, B7-H3, B7-H4, BTLA, VISTA, KIR, A2aR, or TIM3. Activators can also include costimulatory molecules such as CD40, CD80, or CD86. Immunomodulators can also include agents that downregulate the immune system such as antibodies against IL-12p70, antagonists of toll-like receptors TLR-2, 3, 4, 5, 6, 8, or 9, or general suppressors of immune function such as cyclophosphamide, cyclosporin A or FK506. These agents (e.g., adjuvants, activators, or downregulators) can be combined to achieve an optimal immune response.

Immunomodulators of particular interest in the present invention include immune-stimulating agents and immune checkpoint inhibitors. As used herein, the term “immune checkpoint inhibitors,” “checkpoint inhibitors,” and the like refers to compounds that inhibit the activity of control mechanisms of the immune system. Immune system checkpoints, or immune checkpoints, are inhibitory pathways in the immune system that generally act to maintain self-tolerance or modulate the duration and amplitude of physiological immune responses to minimize collateral tissue damage. Checkpoint inhibitors can inhibit an immune system checkpoint by stimulating the activity of a stimulatory checkpoint molecule, or inhibiting the activity of an inhibitory checkpoint molecule in the pathway. Stimulatory checkpoint molecules are molecules, such as proteins, that stimulate or positively regulate the immune system. Inhibitory checkpoint molecules are molecules, such as proteins, that inhibit or negatively regulate the immune system. Immune system checkpoint molecules include, but are not limited to, cytotoxic T-lymphocyte antigen 4 (CTLA-4), programmed cell death 1 protein (PD-1), programmed cell death 1 ligand 1 (PD-L), programmed cell death 1 ligand 2 (PD-L2), lymphocyte activation gene 3 (LAG3), B7-1, B7-H3, B7-H4. T cell membrane protein 3 (TIM3). B- and T-lymphocyte attenuator (BTLA), V-domain immunoglobulin (Ig)-containing suppressor of T-cell activation (VISTA), Killer-cell immunoglobulin-like receptor (KIR), and A2A adenosine receptor (A2aR). As such, checkpoint inhibitors include antagonists of CTLA-4, PD-1, PD-L1, PD-L2, LAG3, B7-1, B7-H3, B7-H4, BTLA, VISTA, KIR. A2aR, or TIM3. For example, antibodies that hind to CTLA-4. PD-1. PD-L1, PD-L2. LAG3, B7-1. B7-H3, B7-H4, BTLA, VISTA. KIR, A2aR, or TIM3 and antagonize their function are checkpoint inhibitors. Moreover, any molecule (e.g., peptide, nucleic acid, small molecule, etc.) that inhibits the inhibitory function of an immune system checkpoint is a checkpoint inhibitor.

The immunomodulator can be of any one of the molecular modalities known in the art, including, but not limited to, aptamer, mRNA, siRNA, microRNA, shRNA, peptide, antibody, anticalin, Spherical nucleic acid, TALEN, Zinc Finger Nuclease, CRISPR/Cas9, and small molecule.

In some embodiments, the immunomodulator is an immune-stimulating agent. In some embodiments, the immune-stimulating agent is a natural or engineered ligand of an immune stimulatory molecule, including, for example, ligands of OX40 (e.g., OX40L), ligands of CD-28 (e.g., CD80, CD86), ligands of ICOS (e.g., B7RP1), ligands of 4-1BB (e.g., 4-1BBL. Ultra4-1 BBL), ligands of CD27 (e.g., CD70), ligands of CD40 (e.g., CD40L), and ligands of TCR (e.g., MHC class I or class II molecules, IMCgp100). In some embodiments, the immune-stimulating agent is an antibody selected from the group consisting of anti-CD28 (e.g., TGN-1412), anti-OX40 (e.g., MEDI6469, MEDI-0562), anti-ICOS (e.g., MEDI-570), anti-GITR (e.g., TRX518, INBRX-110, NOV-120301), anti-41-BB (e.g., BMS-663513. PF-05082566), anti-CD27 (e.g., BION-1402, Varlilumab and hCD27.15), anti-CD40 (e.g., CP870,893, BI-655064, BMS-986090, APX005, APX005M), anti-CD3 (e.g., blinatumomab, muromonab), and anti-HVEM.

Exemplary immune checkpoint molecules and immunomodulators thereof are discussed below. It is understood that other suitable immune checkpoint molecules and immunomodulators known in the art are also within the scope of the present application.

CTLA-4

CTLA-4 is an immune checkpoint molecule, which is up-regulated on activated T-cells. An anti-CTLA-4 mAb can block the interaction of CTLA-4 with CD80/86 and switch off the mechanism of immune suppression and enable continuous stimulation of T-cells by DCs. Examples of anti-CTLA-4 antibodies are Ipilimumab (see U.S. Pat. Nos. 6,984,720, 7,452,535, 7,605,238, 8,017,114 and 8,142,778). Tremilimumab (see U.S. Pat. Nos. 6,68,736, 7,109,003, 7,132,281, 7,411,057, 7,807,797, 7,824,679 and 8,143,379) and other anti-CTLA-4 antibodies, including single chain antibodies (e.g., see U.S. Pat. Nos. 5,811,097, 6,051,227 and 7,229,628, and US Patent Publication No. US20110044953).

Two IgG mAb directed against CTLA-4, Ipilimumab and Tremelimumab, have been tested in clinical trials for a number of indications. Ipilimumab is approved by the FDA for the treatment of melanoma. e.g., for late stage melanoma patients. The complete prescribing information is fully described in the packaging insert of YERVOY® (Bristol Meyers). YERVOY® (Ipilimumab) comes in 50 mg single use vials.

Anticalins are engineered proteins that are able to recognize and bind specific targets with high affinity. They are antibody mimetics, but they are not structurally related to antibodies. Instead, they are derived from human lipocalins, which are a family of naturally binding proteins. Anticalins are being used in lieu of monoclonal antibodies, but are about eight times smaller than monoclonal antibodies with a size of about 180 amino acids and a mass of about 20 kDa. Anticalins have been described in U.S. Pat. No. 7,250,297. Anticalins that bind CTLA-4 with high affinity and specificity have been developed, which are described in, for example, International Patent Application Publication No. WO2012072806. Any of the CTLA-4-binding anticalins may be used in the present application. In some embodiments, the CTLA-4 binding anticalin is PRS-010 (Piers AG).

PD-1

PD-1 is a part of the B7/CD28 family of co-stimulatory molecules that regulate T-cell activation and tolerance, and thus antagonistic anti-PD-1 antibodies can be useful for overcoming tolerance. PD-1 has been defined as a receptor for B7-4. B7-4 can inhibit immune cell activation upon binding to an inhibitory receptor on an immune cell. Engagement of the PD-1/PD-L1 pathway results in inhibition of T-cell effector function, cytokine secretion and proliferation. (Turnis et al., OncoImmunology 1(7):1172-1174, 2012). High levels of PD-1 are associated with exhausted or chronically stimulated T cells. Moreover, increased PD-1 expression correlates with reduced survival in cancer patients.

Agents for down modulating PD-1, B7-4, and the interaction between B7-4 and PD-1 inhibitory signal in an immune cell resulting in enhancement of the immune response. Any of the anti-PD-1 antibodies known in the art may be used in the present invention, for example, see U.S. Pat. Nos. 7,101,550, 5,698,520, 6,808,710, 7,029,674, 7,794,710, 7,892,540, 8,008,449, 8,088,905, 8,163,503, 8,168,757, 8,354,509, 8,460,927, 8,609,089, 8,747,833, 8,779,105, 8,900,587, 8,952,136, 8,981,063, 8,993,731, 9,062,112, 9,067,999, 9,073,994, 9,084,776, 9,102,728, and 7,488,802; and U.S. Patent Publication Nos. US20020055139, US20140044738. For example, Nivolumab is a human mAb to PD-1 that is FDA approved for the treatment of unresectable or metastatic melanoma, as well as squamous non-small cell lung cancer.

PD-L1/PD-L2

PD-L1 (Programmed cell death-ligand 1) is also known as cluster of differentiation 274 (CD274) or B7 homolog 1 (B7-HI). PD-L serves as a ligand for PD-1 to play a major role in suppressing the immune system during particular events such as pregnancy, tissue allographs, autoimmune disease and other disease states such as hepatitis and cancer. The formation of PD-1 receptor/PD-L1 ligand complex transmits an inhibitory signal which reduces the proliferation of CD8+ T cells at the lymph nodes.

Any of the known anti-PD-L1 antibodies may be used in the present invention, see, for example, U.S. Pat. Nos. 7,943,743, 7,722,868, 8,217,149, 8,383,796, 8,552,154, and 9,102,725; and U.S. Patent Application Publication Nos. US20140341917, and US20150203580; and International Patent Application No. PCT/US2001/020964. For example, anti-PD-L1 antibodies that are in clinical development include BMS935559 (also known as MDX-1105), MPDL3280A, MEDI4736, Avelumab (also known as MSB0010718C). KY-1003, MCLA-145, RG7446 (also known as atezolizumab), and STI-A1010.

PD-L2 (Programmed cell death 1 ligand 2) is also known as B7-DC. PD-L2 serves as a ligand for PD-1. Under certain circumstances, PD-L2 and its inhibitor can be used as a substitute for PD-L1 and its inhibitor respectively.

CD40

CD40 (Cluster of differentiation 40) is a co-stimulatory protein found on antigen presenting cells and is required for their activation. Binding of CD40L (CD154) on T_(H) cells to CD40 activates antigen presenting cells and includes a variety of downstream effects to stimulate immune response.

Agents that stimulate the activity of CD40 is useful as an immune-stimulating agent. Any of the known agonistic anti-CD40 antibodies may be used in the present invention, see, for example, U.S. Pat. Nos. 5,786,456, 5,674,492, 5,182,368, 5,801,227, 7,824,683, 6,843,989, 7,618,633, 7,537,763, 5,677,165, 5,874,082, 6,051,228, 6,312,693, 6,315,998, 6,413,514, 6,838,261, 6,843,989, 6,946,129, 7,063,845, 7,172,759, 7,193,064, 7,288,251, 7,338,660, 7,547,438, 7,563,442, 7,626,012, 8,778,345; and U.S. Pat. Publication Nos. US 2003059427, US 20020142358, and US20050136055; International Pat. Publication Nos. WO 02/088186, WO 01/56603, WO 88/06891, WO 94/04570, and WO05/63289; Schlossman et al., Leukocyte Typing, 1995, 1:547-556; and Paulie et al., 1984. Cancer Immunol. Immunother. 17:165-179. For example, agonistic anti-CD40 antibodies that are in clinical development include CP-870,893, Dacetuzumab (also known as SGN-40), and ChiLob 7/4 or APX005M.

OX40

OX40, also known as CD134 and TNFRSF4, is a member of the TNFR-superfamily of receptors. OX40 is a co-stimulatory immune checkpoint molecule, expressed after 24 to 72 hours following activation of the T cells. The interaction of OX40L and OX40 will sustain T cell proliferation and immune response and memory beyond the first two days. Methods for enhancing the immune response to a tumor antigen by engaging the OX40 receptor on the surface of T-cells by an OX40 receptor binding agent, OX40L or an OX40 agonist during or shortly after priming of the T-cells by the antigen can be used in CLIVS as an immune checkpoint inhibitor.

LAG-3

The use of LAG-3 (Lymphocyte Activating Gene-3), and in a more general way, the use of MHC class II ligands or MHC class II-like ligands as adjuvants for vaccines, in order to boost an antigen specific immune response has been successful in pre-clinical models. Antibodies or agents directed against or modulate LAG-3 gene products may be helpful in the present invention. See U.S. Pat. No. 5,773,578, cited and referenced patents for details of LAG-3 related patents and claims.

EXAMPLES

The examples below are intended to be purely exemplary of the invention and should therefore not be considered to limit the invention in any way. The following examples and detailed description are offered by way of illustration and not by way of limitation.

Example 1: Clinical Study of Intratumoral or Intravesical Administration of CG0070 in Combination with Systemic Administration of One or More Immunomodulators

Clinical studies are carried out to evaluate the efficacy and safety of combination therapy comprising local administration of CG0070 and systemic administration of an immunomodulator or a combination (such as 2) of immunomodulators to patients having a solid or lymphatic tumor. For patients having bladder cancer, the CG0070 is administered intravesically. In some cases of solid cancer, patients are administered CG0070 intratumorally.

A variety of immunomodulators are administered individually or in combination to the patients. Any one or more of the immunomodulators of Table 1 may be tested in the clinical studies. The routes of administration, doses, dosing frequencies, duration, and/or maintenance dosing scheme for systemic administration of the immunomodulator(s) can be the same or different from those listed in Table 1. Table 1 is presented here for examples only. Immunomodulators outside the scope of Table 1 can also be evaluated in the clinical studies.

Example 2: A Phase I/II Clinical Study of Intravesical Administration of CG0070 in Combination with Intravesical Administrator of a CTLA-4 Inhibitor and Intravenous Administration of an OX40 Activator in Patients with Muscle Invasive Bladder Cancer

This example describes a clinical study of intravesical administration of CG0070 in combination with intravesical administration of an anti-CTLA-4 antibody, and intravenous administration of an OX40 activator in patients with muscle invasive bladder cancer (MIBC). Muscle invasive bladder cancer is chosen herein as an example because CG0070 has shown to be active in bladder cancer. Furthermore all muscle invasive bladder cancer patients need to have a cystectomy, thus providing a good tumor specimen to prepare the tumor cells needed for this vaccine system. In addition the prognosis of muscle invasive bladder cancer patients (T3-4) has been poor despite the use of neo-adjuvant chemotherapy. Most of these patients are over 60 years of age and few can undergo the serious side effects of chemotherapy. An effective agent that can minimize the risk of disease recurrence in this patient population is an unmet need.

This clinical study is a phase I/II, single-arm, open-label, interventional dose-escalation safety and efficacy study of intravesical CG0070 in combination with intravesical administration of a CTLA-4 inhibitor and intravenous administration of an OX40 activator as a neo-adjuvant therapy in patients with transitional cell muscle-invasive bladder cancer disease, who have been selected for radical cystectomy and pelvic lymphadenectomy. The primary safety objective of the study is to investigate whether CG0070 combined with CTLA 4 blockade and OX40 activation is safe and tolerable for the neo-adjuvant treatment of MIBC patients prior to cystectomy. The primary efficacy objective of the study is to measure tumor PD-L1 or PD-1 level changes after CG0070, CTLA-4 inhibitor, and OX40 activator neo-adjuvant treatment. Secondary study objectives include evaluation of 2-year Disease Free Survival (DFS), 2-year Progression Free Survival (PFS), Overall Survival (OS). Pathological Complete Response proportion at Cystectomy (p0 proportion), Pathological Down Staging Proportion at Cystectomy, and Organ Confined Disease Proportion at Cystectomy.

In the Phase I portion of the study, cohorts of (e.g., three to six) patients receive intravesical CG0070, intravesical CTLA4 inhibitor, and intravenous OX40 activator at one of four dose levels. The first dose level consists of CG0070 and CTLA4 inhibitor alone. Each patient receives 4 weekly installations of intravesical CG0070 (e.g., on Day 1 of each week), and 3 weekly installations of intravesical CTLA-4 inhibitor (e.g., Ipilimumab) from the second week (e.g., on Days 8, 15, and 22), and one installation of intravenous OX40 activator (e.g., GSK3174998) at one of four dose levels in the third week (e.g., on Day 22) with administration of the CTLA-4 inhibitor and the OX40 activator following CG0070.

Dose escalation follows a modified Fibonacci sequence in which the dose increments become smaller as the dose increases. For example, if none of the first three patients in a cohort experiences a dose-limiting toxicity, another three patients will be treated at the next higher dose level. However, if one of the first three patients experiences a dose-limiting toxicity, three more patients will be treated at the same dose level. The dose escalation continues until at least two patients among a cohort of three to six patients experience dose-limiting toxicities (i.e., ≥33% of patients with a dose-limiting toxicity at that dose level). The recommended dose for the next stage or phase of the trial is conventionally defined as the dose level just below this toxic dose level. Dose-limiting toxicity (DLT) is defined with the use of the Common Terminology Criteria for Adverse Events (CTCAE) version 4. A DLT is defined as a ≥Grade 3 drug-related Adverse Events (AE) from day 1 of week 1 to day 1 of week 4 of treatment, including any grade 3 or higher toxicity which requires interruption of study treatment for more than 3 consecutive weeks and/or permanent discontinuation of the drug(s) due to immune-related toxicities, but excluding Grade 3 AE of tumor flare (defined as local pain, irritation, or rash localized at sites of known or suspected tumor) and Grade 3 immune-mediated events of the skin (rash, pruritus) or endocrine systems (hypothyroidism, hyperthyroidism, hypopituitarism, adrenal insufficiency, hypogonadism and Cushingoid syndrome) that resolve to Grade 1 or baseline within 3 weeks with or without the administration of steroids. Hepatic immune toxicity is defined as Grade 3 or higher elevation in aspartate aminotransferase, alanine aminotransferase or total bilirubin. A significant D-dimer increase (20% increase with at least a 1 μg/mL from baseline) in combination with a >grade 2 change in INR, PT, PTT, platelets, or fibrinogen lasting for >7 days is considered a DLT. In addition, clinically significant thrombosis or bleeding related to CG0070 treatment is considered a DLT. Patients with a treatment delay extending beyond 21 days due to toxicity related to study treatment are considered as having a treatment related DLT. For reasons other than treatment related toxicity, patients with a treatment delay extending beyond 7 days or who withdraw from the study before 3 administrations are replaced within the cohort. The maximum tolerated dose (MTD) is the dose immediately preceding that resulting in 2 DLT. If the MTD is not defined, the highest dose administered without 2 DLT will be the Maximum Feasible Dose (MFD). Dose reduction for patients in this study is not allowed. However, if at least 2 out of 6 patients in dose level 1 experience a DLT, three patients will be enrolled at dose level 1. Furthermore, if at least 2 out of 6 patients in dose level 1 experience a DLT, three patients will be enrolled at dose level 2.

A suitable dosage of CG0070 is about 1×10¹² viral particles (vp) once weekly for four weeks. A suitable dosage of the intravesical CTLA-4 inhibitor (e.g., Ipilimumab) is about 0.1 mg/Kg to about 0.3 mg/Kg, but not exceeding 20 mg in total per dose, weekly for three weeks, starting from week 2 and ending on week 4. A suitable dosage of the intravenous OX40 activator (e.g., GSK3174998) is about 0.003 mg/kg to about 10 mg/kg once every three weeks, starting from week 3.

In the Phase II portion of the study, each patient is administered intravesically CG0070 in combination with intravesical administration of the CTLA-4 inhibitor and intravenous administration of the OX40 activator at a dose level determined in the Phase I portion of the study for a four-week treatment course. During both Phase I and Phase II portions of the study, prior to administration of the combination therapy, each patient is assessed for adverse events, and samples (such as blood and urine samples) are collected for laboratory assessment. For example, prior to the first intravesical administration of CG0070, blood and urine samples are collected from each patient to assess GM-CSF level, as well as CG0070 and wildtype adenovirus levels. Prior to each of the week 2, 3, and 4 administrations, samples from patients are collected to for laboratory assessment in hematology (such as CBC with differential, chemistry and coagulation), serum chemistry (such as sodium, potassium, chloride. BUN, creatinine, glucose, total protein, albumin, calcium, total bilirubin, direct bilirubin, alkaline phosphate, LDH, AST. ALT, and thyroid functions), and urinalysis. Vital signs, including blood pressure, pulse, respirations and temperature are recorded prior to each CG0070 treatment and every hour for 2 hours total during the treatment to ensure the patient is clinically stable.

CG0070 and the CTLA-4 inhibitor can be administered as follows. Patients are advised not to drink fluids for 4 hours before treatment and should empty their bladder prior to treatment administration. On the study day, each patient receives pretreatment with a transduction enhancing agent (DDM) administered intravesically via a catheter (Rusch 173430 Foley Catheter & BARD LUBRI-SIL Foley Catheter #70516SI). Pretreatment consists of an intravesical wash with 100 mL normal saline, followed by an intravesical wash with 75 mL of 0.1% DDM. The patient then receive intravesical instillation of 100 mL of 0.1% DDM, which is retained in the bladder for 12-15 minutes and subsequently rinsed with 100 mL of saline. If a patient is unable to tolerate at least 5 minutes of DDM pretreatment, further treatment with CG0070 and CTLA-4 inhibitor should be discontinued for that treatment. If the intravesical infusion of CG0070 is delayed for more than two hours after DDM pretreatment, the patient will not receive CG0070 and must be rescheduled for DDM and CG0070 treatment no sooner than 2 days later. If treatment is delayed for more than 2 weeks, patients must continue to meet eligibility criteria prior to retreatment. Following pretreatment with DDM, each patient receives a single intravesical instillation via catheter (e.g., Rusch 173430 Foley Catheter & BARD LUBRI-SIL Foley Catheter #70516SI) of 100 mL of CG0070 at a concentration of 1.0×10¹⁰ vp/mL with a 45 to 50 minute dwell time. Treatment must occur at least 14 days following any prior bladder biopsy. Patients who experience bleeding during catheter insertion (traumatic catheterization) should not be treated with CG0070. While CG0070 is held in the bladder, the patient should be repositioned from left side to right side and also should lie upon the back and the abdomen to maximize bladder surface exposure to CG0070. The patient position is changed every 10-12 minutes for a total of 45 to 50 minutes. CG0070 is then be drained through the catheter into a disposal bag. As soon as the CG0070 solution has been drained from the bladder, the CTLA-4 inhibitor (for example, Ipilimumab, such as YERVOY®) at the appropriate dosage (e.g., Dose Level I of Phase I study does not include any CTLA-4) is diluted into 100 ml of normal saline, and is instilled into the bladder. After instillation, urethral catheter is then withdrawn and patient is asked to hold for another 45 min to 1 hour (or as long as possible) before emptying by urination.

After the 6-week treatment course in the Phase II portion of the study, each patient receives a cystectomy. Cystectomy is performed 10 to 14 days (e.g., about Day 40) after the last intravesical treatment or as soon as any treatment related toxicity has subsided and medical condition is suitable for surgery. After the cystectomy, tumor specimen is obtained from the patient and assessed in a pathology lab, and laboratory evaluation is performed to determine if the patient has responded to the treatment. This assessment includes pathological and immunological assessments of the resected tumor for: (1) tumor stage and grade, if present; (2) tumor immunological parameters, such as Treg, CD4. CD8 and other T cell subsets; (3) tumor PD-L1 expression status by immunohistochemistry methods; (4) lymph node involvement; (5) macroscopic photo comparison between pre- and post-treatment. Each patient is evaluated at months 3, 6, 12, 18, and 24 (plus or minus 2 weeks) from the date of cystectomy to monitor long-term response and toxicity of CG0070, disease recurrence or progression, and subsequent therapies and response. After 2 years, patients are contacted once a year for assessment of long-term toxicities related to gene therapy (such as new malignancies, autoimmune disease, neurologic and hematologic disorders, etc.), and survival for five years after the first intravesical CG0070 therapy. Patients are followed for up to 5 years in total post treatment with CG0070, or according to current FDA guidelines and the current standard of care.

Primary outcome measures of the study are determined as follows. Patients are followed throughout and upon completion of the study for assessment of AE. SAE, and SUSAR to determine safety and tolerability of the treatment. Additionally, at cystectomy, efficacy of the treatment is assessed by determining the rate of change in PD-L1 and PD-1 status, which is defined as the difference in proportions of patients that are PDL1 or PD1 positive before and after intervention for at least three or more completed intravesical instillations.

Secondary outcome measures of the study are determined as follows. At cystectomy. Pathological Complete Response Proportion at Cystectomy for each T stage (p0 proportion) is assessed by determining the proportion of patients with a pathological complete tumor response at the primary tumor site after intervention at cystectomy stratified further by T staging and for the whole group of patients. Also determined at the time of cystectomy are Pathological Down Staging Proportion at Cystectomy, defined as the proportion of patients with a downgrade of tumor stage or grade at the primary tumor site after intervention at cystectomy; and Organ Confined Disease Proportion at Cystectomy, defined as the proportion of patients with no positive lymph nodes found at cystectomy. Up to 2 years after the cystectomy, patients are followed to determine 2-year Disease Free Survival, defined as the number of months from the date of cystectomy to the earlier of disease recurrence or death (whatever the cause); and 2-year Progression Free Survival for patients with residual disease after cystectomy, defined as the number of months from the date of cystectomy to the earlier of disease progression or death (whatever the cause). Up to five years after the cystectomy, patients are followed to determine Overall Survival, defined as the number of months from the date of cystectomy to the date of death (whatever the cause).

Additionally, exploratory outcome measures to be assessed during the course of the study include, but are not limited to, changes in immune functions within the primary tumor site including assessment of changes in Treg (CD4+CD25+Foxp3+), CD4, CD8, CD4RO45 and CD41COShigh etc. before and after intervention; macroscopic changes in the primary tumor site by photographs taken before and after intervention; systemic absolute lymphocyte counts; and systemic cytokine patterns in the patients.

Example 3: A Phase I/II Clinical Study of Intratumoral Administration of CG0070 in Combination with Intratumoral Administration of a CTLA-4 Inhibitor and Intravenous Administration of an OX40 Activator for Patients with Refractory Injectable Solid Tumors

This example describes a Phase I/II clinical study of CG0070 in combination with a CTLA-4 inhibitor (such as an anti-CTLA-4 monoclonal antibody or blocker) and an OX40 activator (such as an anti-OX40 agonist antibody) for patients with refractory injectable solid tumors. This study is a multi-center, single-arm, open-label, interventional study aimed at evaluating the safety and efficacy of the combination therapy comprising intratumoral administration of CG0070, intratumoral administration of a CTLA-4 inhibitor, and intravenous administration of an OX40 activator in patients with solid tumor, including cutaneous or visceral lesions, such as head and neck squamous cell cancer, breast cancer, colorectal cancer, pancreatic adenocarcinoma, ovarian cancer, non-small cell lung cancer, prostate cancer, and melanoma. The CG0070 administration can include a pretreatment with a transducer, such as DDM.

In Phase I, each subject is administered a combination of CG0070 (e.g., with DDM pretreatment) and the CTLA-4 inhibitor via intratumoral injections weekly (e.g., on Day 1 of each week) for a 6 weeks. Additionally, the subject is administered intravenously an OX40 inhibitor (such as GSK3174998) once every three weeks starting in week 1 at one of three dose levels for 6 weeks. Dose escalation procedure is as described in Example 1. Once the MTD or MFD has been reached, the patients receive repeated 6-week treatment course at 3 month after the first injection and subsequent courses every 3 months until complete response, disappearance of all injectable tumors, confirmed disease progression or intolerance of study treatment, whichever occurs first. Patients who are in the dose escalation phase of the study can be enrolled in the repeat MTD or MFD courses study after a period of three months from the last intervention with full successful enrollment evaluation.

A suitable dosage of intratumoral injection of CG0070 (e.g., with DDM) is about 5×10¹⁰ vp, 1×10¹¹ vp, 5×10¹¹ vp, or 1×10¹² vp weekly for four weeks. For example, the virus CG0070 is reconstituted in 0.1% of DDM in saline. The total volume of each dose is 2 mL. The concentration of the CG0070 solution is about 2.5×10¹⁰ vp/ml for the lowest dose and about 5×10¹¹ vp/ml for the highest dose. If the patient has a single lesion, which must be greater than 2 cm, the total volume of the CG0070 solution is injected into the lesion. If there are two or more lesions, the maximum injection volume based on the lesion size as shown in Table 2 is followed. Any remaining volume is injected into the largest lesion, if the largest lesion is at least 2 cm. If the largest lesion is less than 2 cm, then the remaining volume is divided between the two larger lesions. The maximum number of lesions injected is 3. The total dose is given regardless the total number and size of the lesions.

TABLE 2 Injection volume per lesion based on tumor size Tumor Size Maximum Injection (longest dimension) Volume ≥5.0 cm 2.0 mL ≥2.0 cm to 5.0 cm 1.0 mL >0.5 cm to 2.0 cm 0.5 mL

A suitable dosage of intratumoral injection of the CTLA-4 inhibitor (e.g., Ipilimumab) is about 6 mg to about 18 mg, weekly for six weeks. Immediately after each CG0070 injection, the CTLA-4 inhibitor is administered. The total volume at each dose level, and the maximum injection volumes based on lesion sizes for more than two injected lesions are listed in Table 3 below. The maximum number of injected lesions is 3, and the total dose of the CTLA-4 inhibitor is given regardless the total number and size of the lesions. Any remaining volume of the CTLA-4 inhibitor is administered subcutaneously around the injected lesion(s). In case lesions completely resolved prior to the last planned treatment, both CG0070 and the CTLA-4 inhibitor (e.g., Ipilimumab) can be administered to a previously un-injected lesion. If all lesions are resolved before the end of the treatment course, the CTLA-4 inhibitor (e.g., Ipilimumab) alone can be injected in the subcutaneous area at or around the former lesion.

TABLE 3 Injection volume of immunomodulator per lesion based on tumor size Dose level Tumor Size 6.0 mg 12 mg 18 mg (longest Max dose Max Max dose Max Max dose Max dimension) per lesion Volume per lesion Volume per lesion Volume ≥5.0 cm 6.0 mg 1.2 mL  12 mg 2.4 mL  18 mg 3.6 mL ≥2.0 cm to 5.0 cm 3.0 mg 0.6 mL 6.0 mg 1.2 mL   9 mg 1.8 mL >0.5 cm to 2 cm 1.5 mg 0.3 mL 3.0 mg 0.6 mL 4.5 mg 0.9 mL

A suitable dosage of the intravenous OX40 activator (e.g., GSK3174998) is about 0.003 mg/kg to about 10 mg/kg once every three weeks, starting from week 1.

Dose escalation procedure is as described in Example 1, and MTD/MFD is designated as the study dose, which is used in Phase II.

For Phase II of the study, the cohort of patients first receive a once weekly intratumoral injection of the combination of CG0070 (e.g., with DDM) and the CTLA-4 inhibitor (e.g., Ipilimumab), and intravenous fusion of the OX40 inhibitor (e.g., GSK3174998) once every three weeks starting from week 1 at the study dose determined in Phase I for six weeks. Afterwards, the patients receive repeated 6-week treatment course at 3 month after the first injection and subsequent courses every 3 months until complete response, disappearance of all injectable tumors, confirmed disease progression or intolerance of study treatment, whichever occurs first. Patients who are in the dose escalation phase of Phase I can be enrolled in the Phase II study as long as there is a rest period of at least six weeks from the last dose. For each administration, GC0070 is first injected to the lesions, followed by the CTLA-4 inhibitor (e.g., Ipilimumab), followed by intravenous infusion of the OX40 activator (e.g., GSK3174998).

There are two primary outcome measures for this study: (1) safety and tolerability; and (2) efficacy. Efficacy is assessed by confirmed objective response rate (ORR) of the treatment. The secondary outcome measures of this study are as follows. Safety secondary outcomes are assessed from the beginning of each phase until 24 months following enrollment of the last subject at each phase. Safety secondary outcome measures include incidence of all Adverse Events (AEs), grade 3 or greater AEs, events requiring discontinuation of study drug(s), local effects on tumor, clinically significant laboratory changes and clinically significant changes in vital signs. The efficacy secondary outcomes are assessed from the beginning of each stage until 24 months following enrollment of the last subject at each stage. Efficacy secondary outcome measures include Best Overall Response Rate (BOR), Disease Control Rate (DCR). Durable Response Rate (DRR), Duration of Response (DOR). Time to Response (TTR), Progression Free Survival (PFS). Overall Survival Rate (OS), 1 year and 2 year Survival Rate.

Example 4: A Phase I/II Clinical Study of Intravesical Administration of CG0070 in Combination with Intravesical Administrator of a CTLA-4 Inhibitor and Intravenous Administration of a PD-L1 Inhibitor in Patients with Muscle Invasive Bladder Cancer

This example describes a clinical study of intravesical administration of CG0070 in combination with intravesical administration of an anti-CTLA-4 antibody, and intravenous administration of a PD-L1 inhibitor in patients with muscle invasive bladder cancer (MIBC). Muscle invasive bladder cancer is chosen herein as an example because CG0070 has shown to be active in bladder cancer. Furthermore all muscle invasive bladder cancer patients need to have a cystectomy, thus providing a good tumor specimen to prepare the tumor cells needed for this vaccine system. In addition the prognosis of muscle invasive bladder cancer patients (T3-4) has been poor despite the use of neo-adjuvant chemotherapy. Most of these patients are over 60 years of age and few can undergo the serious side effects of chemotherapy. An effective agent that can minimize the risk of disease recurrence in this patient population is an unmet need.

This clinical study is a phase I/II, single-arm, open-label, interventional dose-escalation safety and efficacy study of intravesical CG0070 in combination with intravesical administration of a CTLA-4 inhibitor and intravenous administration of a PD-L inhibitor as a neo-adjuvant therapy in patients with transitional cell muscle-invasive bladder cancer disease, who have been selected for radical cystectomy and pelvic lymphadenectomy. The primary safety objective of the study is to investigate whether CG0070 combined with CTLA 4 and PD-L1 activation is safe and tolerable for the neo-adjuvant treatment of MIBC patients prior to cystectomy. The primary efficacy objective of the study is to measure tumor PD-L1 or PD-1 level changes after CG0070, CTLA-4 inhibitor, and PD-L inhibitor neo-adjuvant treatment. Secondary study objectives include evaluation of 2-year Disease Free Survival (DFS), 2-year Progression Free Survival (PFS), Overall Survival (OS), Pathological Complete Response proportion at Cystectomy (p0 proportion). Pathological Down Staging Proportion at Cystectomy, and Organ Confined Disease Proportion at Cystectomy.

In the Phase I portion of the study, cohorts of (e.g., three to six) patients receive intravesical CG0070, intravesical CTLA4 inhibitor, and intravenous PD-L1 inhibitor at one of four dose levels. The first dose level consists of CG0070 and CTLA4 inhibitor alone. Each patient receives 4 weekly installations of intravesical CG0070 (e.g., on Day 1 of each week), and 3 weekly installations of intravesical CTLA-4 inhibitor (e.g., Ipilimumab) from the second week (e.g., on Days 8, 15, and 22), and one installation of intravenous PD-L inhibitor (e.g., atezolizumab) at one of four dose levels in the third week (e.g., on Day 22) with administration of the CTLA-4 inhibitor and the PD-L inhibitor following CG0070.

Dose escalation follows a modified Fibonacci sequence in which the dose increments become smaller as the dose increases. For example, if none of the first three patients in a cohort experiences a dose-limiting toxicity, another three patients will be treated at the next higher dose level. However, if one of the first three patients experiences a dose-limiting toxicity, three more patients will be treated at the same dose level. The dose escalation continues until at least two patients among a cohort of three to six patients experience dose-limiting toxicities (i.e., ≥33% of patients with a dose-limiting toxicity at that dose level). The recommended dose for the next stage or phase of the trial is conventionally defined as the dose level just below this toxic dose level. Dose-limiting toxicity (DLT) is defined with the use of the Common Terminology Criteria for Adverse Events (CTCAE) version 4. A DLT is defined as a ≥Grade 3 drug-related Adverse Events (AE) from day 1 of week 1 to day 1 of week 4 of treatment, including any grade 3 or higher toxicity which requires interruption of study treatment for more than 3 consecutive weeks and/or permanent discontinuation of the drug(s) due to immune-related toxicities, but excluding Grade 3 AE of tumor flare (defined as local pain, irritation, or rash localized at sites of known or suspected tumor) and Grade 3 immune-mediated events of the skin (rash, pruritus) or endocrine systems (hypothyroidism, hyperthyroidism, hypopituitarism, adrenal insufficiency, hypogonadism and Cushingoid syndrome) that resolve to Grade 1 or baseline within 3 weeks with or without the administration of steroids. Hepatic immune toxicity is defined as Grade 3 or higher elevation in aspartate aminotransferase, alanine aminotransferase or total bilirubin. A significant D-dimer increase (20% increase with at least a 1 μg/mL from baseline) in combination with a >grade 2 change in INR, PT, PTT, platelets, or fibrinogen lasting for >7 days is considered a DLT. In addition, clinically significant thrombosis or bleeding related to CG0070 treatment is considered a DLT. Patients with a treatment delay extending beyond 21 days due to toxicity related to study treatment are considered as having a treatment related DLT. For reasons other than treatment related toxicity, patients with a treatment delay extending beyond 7 days or who withdraw from the study before 3 administrations are replaced within the cohort. The maximum tolerated dose (MTD) is the dose immediately preceding that resulting in 2 DLT. If the MTD is not defined, the highest dose administered without 2 DLT will be the Maximum Feasible Dose (MFD). Dose reduction for patients in this study is not allowed. However, if at least 2 out of 6 patients in dose level 1 experience a DLT, three patients will be enrolled at dose level 1. Furthermore, if at least 2 out of 6 patients in dose level 1 experience a DLT, three patients will be enrolled at dose level 2.

A suitable dosage of CG0070 is about 1×10¹² viral particles (vp) once weekly for four weeks. A suitable dosage of the intravesical CTLA-4 inhibitor (e.g., Ipilimumab) is about 0.1 mg/Kg to about 0.3 mg/Kg, but not exceeding 20 mg in total per dose, weekly for three weeks, starting from week 2 and ending on week 4. A suitable dosage of the intravenous PD-L1 inhibitor (e.g., atezolizumab) is about 1 mg/kg to about 20 mg/kg (such as about 750 mg to about 1200 mg) at a frequency of about once every two weeks to about once every three weeks, starting from week 3.

In the Phase II portion of the study, each patient is administered intravesically CG0070 in combination with intravesical administration of the CTLA-4 inhibitor and intravenous administration of the PD-L inhibitor at a dose level determined in the Phase I portion of the study for a four-week treatment course. During both Phase I and Phase II portions of the study, prior to administration of the combination therapy, each patient is assessed for adverse events, and samples (such as blood and urine samples) are collected for laboratory assessment. For example, prior to the first intravesical administration of CG0070, blood and urine samples are collected from each patient to assess GM-CSF level, as well as CG0070 and wildtype adenovirus levels. Prior to each of the week 2, 3, and 4 administrations, samples from patients are collected to for laboratory assessment in hematology (such as CBC with differential, chemistry and coagulation), serum chemistry (such as sodium, potassium, chloride. BUN, creatinine, glucose, total protein, albumin, calcium, total bilirubin, direct bilirubin, alkaline phosphate, LDH. AST. ALT, and thyroid functions), and urinalysis. Vital signs, including blood pressure, pulse, respirations and temperature are recorded prior to each CG0070 treatment and every hour for 2 hours total during the treatment to ensure the patient is clinically stable.

CG0070 and the CTLA-4 inhibitor can be administered as follows. Patients are advised not to drink fluids for 4 hours before treatment and should empty their bladder prior to treatment administration. On the study day, each patient receives pretreatment with a transduction enhancing agent (DDM) administered intravesically via a catheter (Rusch 173430 Foley Catheter & BARD LUBRI-SIL Foley Catheter #70516SI). Pretreatment consists of an intravesical wash with 100 mL normal saline, followed by an intravesical wash with 75 mL of 0.1% DDM. The patient then receive intravesical instillation of 100 mL of 0.1% DDM, which is retained in the bladder for 12-15 minutes and subsequently rinsed with 100 mL of saline. If a patient is unable to tolerate at least 5 minutes of DDM pretreatment, further treatment with CG0070 and CTLA-4 inhibitor should be discontinued for that treatment. If the intravesical infusion of CG0070 is delayed for more than two hours after DDM pretreatment, the patient will not receive CG0070 and must be rescheduled for DDM and CG0070 treatment no sooner than 2 days later. If treatment is delayed for more than 2 weeks, patients must continue to meet eligibility criteria prior to retreatment. Following pretreatment with DDM, each patient receives a single intravesical instillation via catheter (e.g., Rusch 173430 Foley Catheter & BARD LUBRI-SIL Foley Catheter #70516SI) of 100 mL of CG0070 at a concentration of 1.0×10¹⁰ vp/mL with a 45 to 50 minute dwell time. Treatment must occur at least 14 days following any prior bladder biopsy. Patients who experience bleeding during catheter insertion (traumatic catheterization) should not be treated with CG0070. While CG0070 is held in the bladder, the patient should be repositioned from left side to right side and also should lie upon the back and the abdomen to maximize bladder surface exposure to CG0070. The patient position is changed every 10-12 minutes for a total of 45 to 50 minutes. CG0070 is then be drained through the catheter into a disposal bag. As soon as the CG0070 solution has been drained from the bladder, the CTLA-4 inhibitor (for example, Ipilimumab, such as YERVOY®) at the appropriate dosage (e.g., Dose Level I of Phase I study does not include any CTLA-4) is diluted into 100 ml of normal saline, and is instilled into the bladder. After instillation, urethral catheter is then withdrawn and patient is asked to hold for another 45 min to 1 hour (or as long as possible) before emptying by urination.

After the 6-week treatment course in the Phase II portion of the study, each patient receives a cystectomy. Cystectomy is performed 10 to 14 days (e.g., about Day 40) after the last intravesical treatment or as soon as any treatment related toxicity has subsided and medical condition is suitable for surgery. After the cystectomy, tumor specimen is obtained from the patient and assessed in a pathology lab, and laboratory evaluation is performed to determine if the patient has responded to the treatment. This assessment includes pathological and immunological assessments of the resected tumor for: (1) tumor stage and grade, if present; (2) tumor immunological parameters, such as Treg, CD4. CD8 and other T cell subsets; (3) tumor PD-L1 expression status by immunohistochemistry methods; (4) lymph node involvement; (5) macroscopic photo comparison between pre- and post-treatment. Each patient is evaluated at months 3, 6, 12, 18, and 24 (plus or minus 2 weeks) from the date of cystectomy to monitor long-term response and toxicity of CG0070, disease recurrence or progression, and subsequent therapies and response. After 2 years, patients are contacted once a year for assessment of long-term toxicities related to gene therapy (such as new malignancies, autoimmune disease, neurologic and hematologic disorders, etc.), and survival for five years after the first intravesical CG0070 therapy. Patients are followed for up to 5 years in total post treatment with CG0070, or according to current FDA guidelines and the current standard of care.

Primary outcome measures of the study are determined as follows. Patients are followed throughout and upon completion of the study for assessment of AE. SAE, and SUSAR to determine safety and tolerability of the treatment. Additionally, at cystectomy, efficacy of the treatment is assessed by determining the rate of change in PD-L1 and PD-1 status, which is defined as the difference in proportions of patients that are PDL1 or PD1 positive before and after intervention for at least three or more completed intravesical instillations.

Secondary outcome measures of the study are determined as follows. At cystectomy. Pathological Complete Response Proportion at Cystectomy for each T stage (p0 proportion) is assessed by determining the proportion of patients with a pathological complete tumor response at the primary tumor site after intervention at cystectomy stratified further by T staging and for the whole group of patients. Also determined at the time of cystectomy are Pathological Down Staging Proportion at Cystectomy, defined as the proportion of patients with a downgrade of tumor stage or grade at the primary tumor site after intervention at cystectomy; and Organ Confined Disease Proportion at Cystectomy, defined as the proportion of patients with no positive lymph nodes found at cystectomy. Up to 2 years after the cystectomy, patients are followed to determine 2-year Disease Free Survival, defined as the number of months from the date of cystectomy to the earlier of disease recurrence or death (whatever the cause); and 2-year Progression Free Survival for patients with residual disease after cystectomy, defined as the number of months from the date of cystectomy to the earlier of disease progression or death (whatever the cause). Up to five years after the cystectomy, patients are followed to determine Overall Survival, defined as the number of months from the date of cystectomy to the date of death (whatever the cause).

Additionally, exploratory outcome measures to be assessed during the course of the study include, but are not limited to, changes in immune functions within the primary tumor site including assessment of changes in Treg (CD4+CD25+Foxp3+), CD4, CD8, CD4RO45 and CD41COShigh etc. before and after intervention; macroscopic changes in the primary tumor site by photographs taken before and after intervention; systemic absolute lymphocyte counts; and systemic cytokine patterns in the patients.

Example 5: A Phase I/II Clinical Study of Intratumoral Administration of CG0070 in Combination with Intratumoral Administration of a CTLA-4 Inhibitor and Intravenous Administration of a PD-L1 Inhibitor for Patients with Refractory Injectable Solid Tumors

This example describes a Phase I/II clinical study of CG0070 in combination with a CTLA-4 inhibitor (such as an anti-CTLA-4 monoclonal antibody or blocker) and a PD-L1 inhibitor (such as an anti-PD-L1 antagonist antibody) for patients with refractory injectable solid tumors. This study is a multi-center, single-arm, open-label, interventional study aimed at evaluating the safety and efficacy of the combination therapy comprising intratumoral administration of CG0070, intratumoral administration of a CTLA-4 inhibitor, and intravenous administration of a PD-L1 inhibitor in patients with solid tumor, including cutaneous or visceral lesions, such as head and neck squamous cell cancer, breast cancer, colorectal cancer, pancreatic adenocarinoma, ovarian cancer, non-small cell lung cancer, prostate cancer, and melanoma. The CG0070 administration can include a pretreatment with a transducer, such as DDM.

In Phase I, each subject is administered a combination of CG0070 (e.g., with DDM pretreatment) and the CTLA-4 inhibitor via intratumoral injections weekly (e.g., on Day 1 of each week) for a 6 weeks. Additionally, the subject is administered intravenously a PD-L1 inhibitor (such as atezolizumab) about once every two weeks to about once every three weeks starting in week 1 at one of three dose levels for 6 weeks. Dose escalation procedure is as described in Example 1. Once the MTD or MFD has been reached, the patients receive repeated 6-week treatment course at 3 month after the first injection and subsequent courses every 3 months until complete response, disappearance of all injectable tumors, confirmed disease progression or intolerance of study treatment, whichever occurs first. Patients who are in the dose escalation phase of the study can be enrolled in the repeat MTD or MFD courses study after a period of three months from the last intervention with full successful enrollment evaluation.

A suitable dosage of intratumoral injection of CG0070 (e.g., with DDM) is about 5×10¹⁰ vp, 1×10¹¹ vp, 5×10¹¹ vp, or 1×10¹² vp weekly for four weeks. For example, the virus CG0070 is reconstituted in 0.1% of DDM in saline. The total volume of each dose is 2 mL. The concentration of the CG0070 solution is about 2.5×10¹⁰ vp/ml for the lowest dose and about 5×10¹¹ vp/ml for the highest dose. If the patient has a single lesion, which must be greater than 2 cm, the total volume of the CG0070 solution is injected into the lesion. If there are two or more lesions, the maximum injection volume based on the lesion size as shown in Table 2 is followed. Any remaining volume is injected into the largest lesion, if the largest lesion is at least 2 cm. If the largest lesion is less than 2 cm, then the remaining volume is divided between the two larger lesions. The maximum number of lesions injected is 3. The total dose is given regardless the total number and size of the lesions.

A suitable dosage of intratumoral injection of the CTLA-4 inhibitor (e.g., Ipilimumab) is about 6 mg to about 18 mg, weekly for six weeks. Immediately after each CG0070 injection, the CTLA-4 inhibitor is administered. The total volume at each dose level, and the maximum injection volumes based on lesion sizes for more than two injected lesions are listed in Table 3 below. The maximum number of injected lesions is 3, and the total dose of the CTLA-4 inhibitor is given regardless the total number and size of the lesions. Any remaining volume of the CTLA-4 inhibitor is administered subcutaneously around the injected lesion(s). In case lesions completely resolved prior to the last planned treatment, both CG0070 and the CTLA-4 inhibitor (e.g., Ipilimumab) can be administered to a previously un-injected lesion. If all lesions are resolved before the end of the treatment course, the CTLA-4 inhibitor (e.g., Ipilimumab) alone can be injected in the subcutaneous area at or around the former lesion.

A suitable dosage of the intravenous PD-L1 inhibitor (e.g., atezolizumab) is about 1 mg/kg to about 20 mg/kg (such as about 750 mg to about 1200 mg) at a frequency of about once every two weeks to about once every three weeks, starting from week 1.

Dose escalation procedure is as described in Example 1, and MTD/MFD is designated as the study dose, which is used in Phase II.

For Phase II of the study, the cohort of patients first receive a once weekly intratumoral injection of the combination of CG0070 (e.g., with DDM) and the CTLA-4 inhibitor (e.g., Ipilimumab), and intravenous fusion of the PD-L1 inhibitor (e.g., atezolizumab) about once every two weeks to about once every three weeks starting from week 1 at the study dose determined in Phase I for six weeks. Afterwards, the patients receive repeated 6-week treatment course at 3 month after the first injection and subsequent courses every 3 months until complete response, disappearance of all injectable tumors, confirmed disease progression or intolerance of study treatment, whichever occurs first. Patients who are in the dose escalation phase of Phase I can be enrolled in the Phase II study as long as there is a rest period of at least six weeks from the last dose. For each administration, GC0070 is first injected to the lesions, followed by the CTLA-4 inhibitor (e.g., Ipilimumab), followed by intravenous infusion of the PD-L1 inhibitor (e.g., atezolizumab).

There are two primary outcome measures for this study: (1) safety and tolerability; and (2) efficacy. Efficacy is assessed by confirmed objective response rate (ORR) of the treatment. The secondary outcome measures of this study are as follows. Safety secondary outcomes are assessed from the beginning of each phase until 24 months following enrollment of the last subject at each phase. Safety secondary outcome measures include incidence of all Adverse Events (AEs), grade 3 or greater AEs, events requiring discontinuation of study drug(s), local effects on tumor, clinically significant laboratory changes and clinically significant changes in vital signs. The efficacy secondary outcomes are assessed from the beginning of each stage until 24 months following enrollment of the last subject at each stage. Efficacy secondary outcome measures include Best Overall Response Rate (BOR), Disease Control Rate (DCR), Durable Response Rate (DRR), Duration of Response (DOR), Time to Response (TTR). Progression Free Survival (PFS), Overall Survival Rate (OS), 1 year and 2 year Survival Rate.
